Amr ibn Jurmuz

Amr ibn Jurmuz was an Arab man who sided with Ali during the First Fitna. In 656, he tracked down Aisha's general Zubayr ibn al-Awam shortly before the Battle of the Camel, finding him praying in a field. Amr told Zubayr that he was also going to pray, but he stabbed Zubayr through the neck as Zubayr prostrated as a sign of respect to God.
